The government ramped up measures against the coronavirus epidemic following new predictions that the UK could otherwise have seen 250,000 deaths.
A new document published by the COVID-19 team at London's Imperial College - which is advising the government on its coronavirus response - warns the current public health threat is the "most serious" from a respiratory virus since the Spanish Flu in 1918.
They advised the UK adopts a strategy of "epidemic suppression" - for a period of potentially 18 months or more - rather than "mitigation".
As a result, the govt is now switching to suppression which is containment the first step - which all the other countries have been following from the start.
